I am really not playing with words :). We really have zero desire in working on the text editor. Just like we had zero desire in working on Sparta and Bloc. We are doing it because we need a sane infrastructure. We have halted the work on user interface of GT for more than 1 year just because it did not make engineering and economic sense to invest on the current infrastructure. We need an infrastructure to support at least the next 5-10 years of development, and we are decided to deliver on it. The investment in TxText is not at all wasted, it allowed us to bootstrap Bloc and to learn. We might end up with reusing parts of it, but the thing is that now we have new opportunities that come with Sparta. For example, all text measurements are super accurate and are available in image. This means that we can address text rendering in two ways: 1. treat text as one entity and embed graphics inside as elements in the text model. This is where TxText is. However, TxText does not have the support for non-text elements (at least not now). Furthermore, this approach makes floating images inside the text (images that allow text to wrap around) to not be really working. 2. split the text in different sections and lay it out together with other graphical elements using the layout engine from Bloc. Option 2 was not really an option until now because we did not have the performance and accuracy. Now it is an option and we want to investigate this as well before committing to a model.
